Divided and this application Novemher 4, 1941, SerialNo. 417,819 r 7 Claims. (01. 2731-4065) This invention relates to a dart and more particularlyto a dart utilizing sheet material in the manufacture thereof. 1 T

*An object of this invention is to provide a dart wherein the main body portion thereof is made from sheet material. v

Another object of this invention is to provide a dart that is. easily produced, economical to manufacture, efiicient, dependable and safe to manipulate, wherein the dart protective head.

Another object of this invention isto provide a paper dart having a suction cup attached thereto. 1 i

Another object of this invention is to provide a dart made from folded sheet material at tached toa suction cup. y 1

Other objects and advantagesreside in the con struction of parts, the combination thereof and the mode of operation, as will become more apparent from the following description.

is provided with a for the neckZZ of the dart, which neckjprojects tween the sides I4, forms a reenforcing portion into a slotted opening or hole in the suction cup iii. The neck 22 is enlarged at the outer end, so as to form an anchor seated in the slot inthe suction cup it. Although the neck isenlarged and thereby anchored in the slot in thesuction cup, it is necessary for some purposes to cement the neck 22 in the slot of the suction cup.

Instead of cementing the neck, a suitable reenforcing member may be wedged between the folded portions of the neck, so as to cooperate with the enlarged end to rigidly anchor the tail portion. in the suction cup. This reenforcing member may project between the sides of the tail portion, so as to g'ive the sides rigidity. The rear ends of the sides I4 are inclined at Mb, as to form a band engaging seat, as will appear more fully later. This dart assembly isprojected from a suitable catapult, which will be briefly described. i

The catapult is preferably made from a cardboard blank 30 having a pair of overlapping portions or flaps 34 folded upon the main body portion 36 and held in position by a staple 38. The overlapping portions, 34 cooperate to form a longitudinal slot having a cross sectional area simulating an inverted T, in which slot the dart is seated immediately prior to being projected. The forward end of the main body portion is provided with an extension 40, having a pair of slots 42 adapted to receive a rubber band 44. Before Figure 5 is a perspective view looking at the No. 403,701 filed July 23,

1941, for Catapult, ripening into Patent No. l

2,264,807 on December 2 1941.

The catapult dart assembly shown herein consists broadly of a dart or a projectileand a catapult therefor, which will now be described.

loading, this rubberband is stretched so as to 1 have the loop positioned under a band retaining extension. 46 projecting from the opposite end of the catapult.

As clearly shown in Figure 1, when the rubber band 44 has been positioned in engagement with the extension 46, the dart is inserted in the slot The projectile or dart assemblyincludes a head portion, which consists of a cup H), and atail portion I2.

I2 is made from suitable sheet example, a good grade of paper The tail portion material, as for orlight weight vacuum or suction cardboard. The entire tailportionconsists of a 1 single piece made from a blank as shown inFigure 3. This tail portion includes apair of side members [4 formed by folding the blank along the line I 4a. The side members l4 merge into coplanar wing portions l6 extending outwardly from the creases 'or score lines 16a. The plane of the wing I6 is offset from thesuction cup, so as to permit the use of-a catapult for projecting the dart, as will appear more fully later.

As may be seen by referring to Figures 3' and 4, the tail portion is reenforced by an extension l8 that is folded on the score or fold line 20.

This extension 5, when folded into the bight beformed between the overlapping portions 34 and seated near the lower end of the catapult, with the wings I 5 of the dart positioned in channels found between-the overlapping portions 34 and the main body portion 36. The rubber band may then be released from the extension 46, causing it to snap into engagement with portion of the dart, so as to the catapult. I

As soon as the dart leaves the catapult, the wings l6, extending outwardly, guide the dart,

shoot the dart from causing it to shoot through the air. The suction cup I0 functions as a weight and the tail portion l2 of the dartfunctions as a taiL'causing the suctioncup to head the dart. If the suction cup alights withsuflicient momentum on a "smooth surface substantially normal to its direction of flight, the suction cup will stick to the smooth surface, holding the dart in the position inwhich it alights.

This dart is easily manufactured from cheap the band receiving materials, requiring few parts that are assembled with a very few manual operations. At the same time, the resulting structure is very attractive as an amusement toy.

The type and grade of material used, the weight and-the size thereof are a matter of choice, depending entirely upon the ultimate use to which the dart is to be put. Instead of using cardboard for the sheet material parts, these may be made from sheet metal or any other suitable sheet material having the desired characteristics.

Although the preferred modification of the device has been described, it will be understood that within the purview of this invention vvarious changes may be made in the form, details, proportion and arrangement of parts,'the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
